Earth's orbit is an ellipse with the Sun at one of the foci. Perihelion is the point at which Earth is closest to the Sun, and aphelion is the point at which it is farthest from the Sun. The distances from perihelion to the Sun and from the Sun to aphelion are in an approximate ratio of 59:61. If the total distance from aphelion to perihelion along the major axis is about 186 million miles, approximate
a. The distance from perihelion to the Sun.
b. The distance from aphelion to the Sun.
c. The distance from aphelion to the center.
d. The distance from the center to the Sun.
e. In this ellipse it can be shown that the distance from the Sun to point P equals the distance from aphelion to the center. Using this information, find the distance from the center to P.
f. Write an equation that models the orbit of Earth around the Sun.

These four circular snow sculptures by British environmental sculptor Andy Goldsworthy (b 1956) were made from bricks of packed snow at the Arctic Circle.
